Abstract

A shower head, for example, a hand shower contains in its interior a means with which the flow of the water leaving the shower head through a jet orifice can be modulated relatively slowly. The means for modulating the flow of water may be powered, more particularly, by a turbine wheel arranged in the interior of the shower head. When two arrays of jet orifices are provided for producing two different types of jet the means may be used for automatic changeover between the two types of jet. The invention provides a shower with which the user is showered by all types of jet possible with the aid of the shower without requiring him to make a change by hand.

Claims

1. A shower head comprising:

a housing with a water inlet leading into the housing, a jetting disk having at least one jet orifice therein, a water guide for guiding water from said water inlet to said at least one jet orifice;

an automatic operating means for cyclically modulating flow of water jetted from said at least one jet orifice; and

,

wherein two arrays of jet orifices and a water guide are provided, leading to each array respectively, and wherein the means for cyclically modulating the flow is configured to switch to and fro between the two arrays of jet orifices.

2. The shower head as set forth in claim 1, wherein said means for cyclically modulating the flow is configured such that in reducing an effective cross-section of one said water guide, it increases that of the other said water guide.

3. The shower head as set forth in claim 1, further comprising a restrictor inserted in said water guide.

4. The shower head as set forth in claim 3, wherein said means for cyclically modulating the flow is motor powered.

5. The shower head as set forth in claim 4, wherein said means for cyclically modulating the flow is water powered.

6. The shower head as set forth in claim 5, wherein said means for cyclically modulating the flow comprises a turbine wheel geared to said restrictor.

7. The shower head as set forth in claim 3, wherein said restrictor comprises two parts that are movable relative to each other, each of said parts having at least one port, a total projection surface of said parts defining a cross-section of said water guide.

8. The shower head as set forth in claim 7, wherein both said parts comprise flat disks and at least one of the disks is rotatable.

9. The shower head as set forth in claim 8, wherein said two arrays of jet orifices are arranged concentrically and at least one of said two disks comprises a port oriented in direction of movement for each said water guide, respectively.
